A study of Norwegian science textbooks for grade 8 indicates an individualistic image of science where individual scientists are discovering truth, through experiment. Scientific rationality is grounded in procedures of inquiry alone and not in debate and argumentation within scientific communities. The communal aspects of science tend to become visible in historical examples where science did not function properly due to prejudices or ignorance. Furthermore, science proper and school science are not differentiated between, and 'scientific knowledge about nature' and 'nature' are one and the same. The discourse identified is well suited to provide students with broad and general knowledge about natural and everyday phenomena. However, it is less suitable for teaching about the scientific enterprise in contemporary society. This is worrying for students' scientific literacy as future adults, as this dimension is essential for understanding the nature of science and for democratic citizenship in socio-scientific issues. 相似文献

Recently, March, Hooper, and Baum (1977) described a sample of 99 nonstudent elders in terms of their demographic characteristics and their attitudes toward lifelong learning. The sample was found to be well‐educated (mean years of education = 13.61, SD = 9.43), active in the community, well‐read, and fairly affluent. The majority demonstrated a quite open attitude toward the appropriateness of formal education in old age, but also felt that learning can be acquired outside the classroom: “living is learning.” The present study was undertaken to similarly describe a sample of elderly people enrolled in the University of Wisconsin guest student program, and to contrast these respondents with those in the earlier study. The student group was found to be significantly younger than the nonstudent group (mean = 70.78, SD = 7.21 vs. mean = 74.69, SD = 8.45; t = 2.87, p < .001). Although there is no difference in the mean years of education of the two groups, there is significantly greater variability in years of education in the student group (F = 10.98, p < .001), with 50.4% of the nonstudent group versus 21.6% of the student group having 12 years of education or less. Additionally, it was found that only 10 of the 139 student respondents did not have either personal or vicarious personal (through familial significant others) experience with higher education in youth. The respondents’ stated preference for class format and student group age is also summarized, and some implications for educational gerontology are discussed. 相似文献

During the coming years the number of older adults will increase dramatically, which will require a corresponding increase in the number of social workers who have accurate knowledge of this population. This article reports the impact focus groups with older adults and with service providers who work with older adults and their families have on baccalaureate social work (BSW) students. We find that BSW students exposed to focus groups have their negative attitudes about older adults and service providers deconstructed and replaced with more positive and accurate information about older adults. When students' misconceptions about older adults are confronted, they become more interested in choosing geriatric social work as a career option. 相似文献

Businesses and educational institutions use satellite technology to transmit information for a number of purposes, including training. This study assessed the effectiveness of a satellite training program for achieving various learning requirements ranging from recognition and recall of information to the performance of a specific job procedure. This study also compared satellite training with traditional classroom training for two courses in which the same material was taught using both media. Results showed that learning occurred using the satellite medium and that there were slight but statistically significant differences between satellite and classroom instruction for learning job-related skills.Kristen M. Williams is a senior member of AIR's research staff specializing in training research and evaluation.
